In a surreal world where hearts are treated like commodities, players assume the role of Valentine, a sarcastic heart broker who navigates the bizarre underworld of emotions and desires. Players must interact with eccentric characters, uncover secrets about their own heart's origin, and negotiate for the best 'heart trades' to uncover hidden truths. As choices lead to unexpected twists, players must determine whose heart they truly want—while avoiding those eager to take it for themselves.
